Answer:
d^2 = 30^2 + 12^2
e^2 = d^2 + 8^2
e^2 = 30^2 + 12^2 + 8^2
e = √(30^2 + 12^2 + 8^2) = 33.3 ft

Step-by-step explanation:
Answer:
Population is the total number of people that fall into the description of those that the research concerns.
In this case, Population is: Everyone who signed a card saying that they intend to quit smoking.
Sample. This is a subset of the population that the research is based on.
Sample = 1,000 people surveyed.
Parameter and Statistic are both descriptive measures but parameter is for the population and statistic is for the sample.
Parameter = Percentage of total population who have not smoked in 6 months.
Statistic = 21% of sample who have not smoked in 3 months.
Anyways the center will be (-9;6)
Answer:
c =1/2
Step-by-step explanation:
2(3–5c) = 4(1–c) -1
Distribute
6 - 10c = 4 -4c -1
Combine like terms
6 - 10c =3 -4c
Add 10c to each side
6-10c+10c = 3 -4c+10c
6 = 3+6c
Subtract 3 from each side
6-3 = 3-3+6c
3 = 6c
Divide by 6
3/6 =6c/6
1/2 =c
